For the benefit of frequent travelers, Bell & Ross fitted the Vintage BR 123 with dual time zone display.

The GMT (Greenwich Mean Time) function allows two time zones to be displayed simultaneously. The metal hands on the main dial display the time in the first time zone; the orange hand gives the time in the second zone, shown on the graduated 24-hour outer bezel. The large figures, the hands with photo-luminescent coating and the orange color of the GMT hand ensure perfect legibility both day and night.
